High-Quality Brake Lines – Durability and Performance You Can Trust

In this category, you’ll find a comprehensive selection of brake lines and fittings for your vehicle’s braking system. Brake lines are essential for efficiently transferring brake fluid from the master cylinder to the calipers. At DDESIGN, we know that both performance and durability are crucial, which is why we only offer products of the highest quality.


Our brake lines are made from robust materials such as stainless steel and copper-nickel alloys, ensuring excellent resistance to corrosion and long-lasting durability, even under extreme conditions. These materials are specifically chosen to withstand high temperatures and pressures, giving you confidence and safety during the most demanding motorsport events.


How to Replace Brake Lines

Replacing brake lines requires proper knowledge and the correct procedure to ensure your braking system functions safely. We recommend following these steps:

  1. Lift and secure the vehicle – Make sure the car is properly lifted and safely supported to give you access to the braking system.
  2. Drain the brake fluid reservoir – Use a suitable hand pump to empty the reservoir to prevent leaks and air from entering the system during replacement.
  3. Loosen the brake lines – Use the proper tools to loosen the fittings securing the brake lines. Be careful not to damage any other parts or components in the process.
  4. Install new brake lines – Fit the new lines securely, ensuring all connections to the master cylinder and calipers are tight and leak-free.
  5. Refill brake fluid – Once the new lines are in place, refill the reservoir to the correct level and check for leaks. Bleed the brakes if necessary.

We strongly recommend consulting a professional mechanic if you’re unsure about replacing brake lines yourself. Always follow the manufacturer’s instructions and use the correct tools and equipment for a safe and proper installation.

Safety and Performance in Focus – Effective Brake Cleaning

In racing conditions, having brakes that perform at their best - and remain clean and free from debris - is critical. In our brake cleaning category, you’ll find the best products to effectively clean and maintain your braking system.


Our brake cleaners are specially formulated to dissolve and remove residue caused by heavy use and high temperatures. They effectively remove dirt, oil, brake dust, and other contaminants from calipers, rotors, and other brake components. Regular use of these products can improve braking performance and extend the lifespan of your components.


How to Clean Brakes

Cleaning your brakes is an important part of system maintenance and can be done by following these steps:

  1. Preparation – Park your vehicle on a flat surface and ensure the engine is off. Loosen the wheel nuts and lift the car to access the brakes.
  2. Apply brake cleaner – Spray a generous amount of brake cleaner on the calipers, rotors, and other brake parts. Make sure all surfaces are covered to dissolve grime and buildup.
  3. Wait and wipe – Let the cleaner work for a few moments, then wipe the components with a clean cloth or use compressed air to remove dirt and residue.
  4. Inspect – Carefully check for wear, damage, or leaks. Replace any worn parts or consult a mechanic for further action if needed.

Note: Always use proper personal protective equipment when handling brake cleaner. Wear gloves and work in a well-ventilated area to avoid exposure to chemicals.
